Design and implementation of a PC-based data acquisition system for measuring ECG and respiratory signals.
A PC-based system capable of measuring R-R intervals in the electrocardiogram and detecting respiration phases is presented. It consists of standard amplifiers for ECG and respiration signals and a personal computer that detects QRS complexes, inspiration and expiration using low-pass, high-pass and differentiation processes. The performance of the method is evaluated using an application for real ECG and respiratory data.
